ISSUE WITH THE FACEBOOK LOGIN ON JOMSOCIAL. IN. USERS SHOULD BE ABLE TO LOGIN WITH FACEBOOK AND INVITE ALL THERE FACEBOOK FRIENDS OR SELECTED ONES TO JOIN SITE. ALSO NEED FACEBOOK LOGIN ON HOME PAGE 3. HOME TAB ON THE MAIN MENU WHEN CLICKED GOES TO AN ERROR PAGE. YOU WILL NOTICE THAT IF YOU ARE ON THE NETWORK PAGE AND THEN CLICK THE SMALL HOME BUTTON THAT IS BELOW THE BIGGER ONE ON THE TOP OF THE PAGE IT WILL GO TO AB ERROR PAGE DONT KNOW IF THIS AFFECTS ANYTHING BUT THE FILES FOR THE SITE ARE SET IN THE VIDEO FOLDER.
